How high: I got taken roughly about 10 foot up and travelled horizontally 20 foot or so. I didn't drop the kite too low in the window because only weighing in at 10 stone I was scudding too much when I attempted it and couldn't hold myself static and the kite back for a bigger sudden boost. If I had weighed more I could possibly have gone higher (ironically enough). Bridle issue: Funnily enough, we got stopped by a guy on the beach asking the same thing about the bridle but I can't say I've had any problems with it. I've only used it for a few days though so maybe it will show at some stage but as of yet, no problems.
